- SHOCK ABSORBER AND BUMPER FOR THE TONGUES AND DOUBLETREE EQUALIZERS 0FCULTIVATORS Filed 'July 30, 1928 Attorney Patented Nov. Zti, 1929 litreHERMAN A. STEPHENS, 0F STERLING, COLORADO SHOCK ABSORBER AND BUMPERF011, THE TC'NG'UES AND DO'UBLETREE EQUALIZERS OF CULTIVATOR$Application filed July 30,

The present invention relates to a device for use on a go dig,particularly designed for farm use in cultivating corn, when the corn isplanted by a lister.

The device absorbs the jerkin and bumping which takes place between theaxle and the double tree equalizer of the machine which is very hardupon the horses drawing the machine.

Another very important object of the invent-ion resides in the provisionof a cevice of this nature which is exceptionally simple in itsconstruction, inexpensive to manufacture, strong and durable, andthroughly efficient and reliable in use.

With the above and numerous other objects in view, as will appear as thedescri tion proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of partsas will behereinafter more fully described and claimed.

In the drawing:

Figure 1 is a perspective view of a machine with my device mounted onthe tongue thereof.

Figure 2 is a fragmentary detail view of the tongue, showing the devicein place, and

Figure 3 is a perspective view of the device.

Referring to the drawing in detail, it will be seen that the numeral 5denotes the cult-ivating apparatus, havin the usual tongue 9, doubletree or evener 6, clevis 8, whifiletree 7, double tree evener supp rt10, and pull rods 11. The tongue 9 is rigidly connected to the frame ofthe machine. Tie support 10 is pivotally connected to the tongue so asto be capable of swinging in the direction of the length of the tongueWhile the rods 11 are interposed between and connected to the support 10and the axle of the cultivator inside of the wheels illustrated. Mydevice is preferably made of iron or steel and is fastened to the tonguewith bolts or in any other suitable manner. This device is disposed justabove the clevis 8 and is adapted to be abutted by the clevis 8 when thedraft animals pull from the whiilletrees 7.

Specifically described, my improved device includes a bar having astraight central por- 1928. Serial No. 296,218.

absence of my improvement, the 0;. the cultivator riding over rough soilso the support 10 to move and hit the tongue 9 and jerk on the necks ofthe draft When, however the bar 12 is proed at the underside of thetongue 9 and opposed to the clevis 8, as clearly shown in Figure 1, thestriking of the element 10 against the tongue 9 will be averted as willalso the jerking on the necks of the draft animals. This will be betterunderstood when it is stated that at all times the clevis 8 is inengagement with the bar 12 and that all thrust of the clevis 8 r ceivedfrom the element 10 is immediately imposed on the bar 12.

The present embodiment of the invention has been disclosed inconsiderable detail, for the purpose of exempliiication, because itcontains the arcs of advantage enumerated as 'rable in the statement ofthe invention the abo e description.

will be apparent that changes in the deof construction, in the sizes anddimen- '--s and proportions of parts ma be re- "bout departing from thespirit or scope or the invention as hereinafter claimed or sacrificingany of its advantages.

Having thus described my invention, What claim as new is:

u ater, the combination with a wl eels supporting said frame, a tongueconnec ed to the frame, a clevis of L d below and spaced from the shapedclevis support interlocked ie bght of the clevis and swingably on withand pendent from the tongue, cs i terposed between and connected bearingportion of the cultivator clevis support, and a double tree arranger,Jelov: he tongue in spaced relation thereto and disposed in andconnected to the clevis; of a bar having an imperforate longitudinalportion spaced below the tongue and opposed to and engaged by the clevisand also having end portions arranged against and connected to thetongue.

In testimony whereof I aflix my signature.

HERMAN A. STEPHENS.
